Description
Data structure that defines and controls an aggregation
of data structures, collectively known as a packet.
Includes information about every packet in the
system.
Data structure that describes a particle and may be
chained to other particles in a linked list. Includes
information about the actual data of the packet and
other particle headers in this packet if present in this
packet.
Duplicate particle header that points to a previously
allocated particle. Differs from a particle header in
that a particle clone shares the particle with another
particle header.
Scratch pad shared among the features in the packet
path, listing hangs of the packet header.
